Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni3(HITP)2-coated interdigitated micro-supercapacitors show high-rate pseudocapacitive behaviour and stable CV response over 1000 cycles.
Caveat: Application metrics are for a Pt/Ni3(HITP)2 device in KOH, not intrinsic MOF electrical transport.
7-9 · Results and Discussion/Conclusion · Figure 6 · Linked to 6 structured results
The optimised anodic deposition method forms Ni3(HITP)2 films on multiple conductive 2D substrates and 3D templates, enabling integration into microdevices.
Caveat: Morphology varies strongly with substrate roughness, wettability and electrocatalytic effect.
5-7 · Results and Discussion · Figures 4, 5 · Linked to 4 structured results
Despite the conductive-MOF framing, this paper does not report a first-hand electronic conductivity value for the electrodeposited Ni3(HITP)2 films.
Caveat: The paper cites literature conductivity potential for conductive MOFs and uses electrochemical rate/EIS data as application evidence.

Pt@Ni3(HITP)2 core-shell nanowires are expected to improve electrical conductivity and mechanical stability relative to bulk Ni3(HITP)2 by combining Pt and MOF in one nanostructure.
Caveat: The benefit is stated as expected; no direct first-hand electronic conductivity comparison is reported.
6 · Results and Discussion · Figure 5A · Linked to 2 structured results
Optimised potentiostatic/pulsed electrodeposited films are assigned to Ni3(HITP)2 with no observed PXRD impurity peaks, no unreacted ligand by ATR-IR, and no Ni0/Ni(OH)2/NiO signatures by XPS.
Caveat: Absence claims are limited by detection limits; XPS peak labels appear swapped in the text but purity conclusion is clear.
5 · Results and Discussion · Figures 3, S6, S7 · Linked to 4 structured results
Pulsed potentiostatic deposition in MeOH-DMSO gives more uniform, finer-grained crystalline Ni3(HITP)2 films and was selected for device integration.
Caveat: Selection is comparative/qualitative; exact grain-size distributions are not tabulated.
5 · Results and Discussion · Figures 2D, 3 · Linked to 2 structured results
Direct non-sacrificial anodic electrodeposition couples charge transfer and Ni3(HITP)2 growth at the MOF/electrolyte interface while avoiding sacrificial metal dissolution.
Caveat: Mechanistic assignment is based on CV, controls and morphology rather than in situ spectroscopy.
3 · Results and Discussion · Scheme 1C-D · Linked to 3 structured results
In the absence of electrochemical oxidation, molecular oxygen acts as the oxidant for chemical Ni3(HITP)2 formation; inert conditions suppress the reaction.
Caveat: Based on visual SI control reaction over two hours at 65 C.
